Dorumon is the star of the 8th Digimon movie that is completely computer animated. The title of the
movie is "Digital Monsters X-Evolution: The 13th Royal Knight," ("X-Evo" or "Digimon X" for
short). In the movie, Dorumon is an outcast because he carries the X-Antibody, which makes
him immune to the genocide program launched by the Royal Knights. Dorumon doesn't understand
why he is hated so much, only that others don't like Digimon that hold the X-Anitibody.
Dorumon becomes friends with WarGreymon, MetalGarurumon, Tokomon, and others. Dorumon finds
out that he was created by Yggdrasil. In the end Dorumon evolves into Alphamon, the leader
of the Royal Knights and then kills himself in order to kill his "shadow" Death-X-Dorugoramon
